The Times, Frank Pope: The wreck of HMS Victory, a British warship sunk in the English Channel in 1744, is being destroyed by fishing trawlers, according to the American treasure hunters who discovered the site last year.

“We were shocked and surprised by the degree of damage we found in the Channel,” said Greg Stemm, chief executive of Odyssey Marine Exploration.

“When we got into this business, like everyone else we thought that beyond 50 or 60 metres, below the reach of divers, we’d find pristine shipwrecks. We thought we’d be finding rainforest, but instead found an industrial site criss-crossed by bulldozers and trucks.”

Odyssey - the world’s only publicly-listed shipwreck exploration company - surveyed 4,725 sq miles (12,300 sq km) of the western Channel during its search for high-value shipwrecks. It discovered 267 wrecks, of which 112, or 41 per cent, show evidence of damage from a type of fishing known as bottom trawling.

The site of HMS Victory shows nets and cables snagged around cannon and ballast blocks. Three bronze cannon were displaced. One, a 42-pounder weighing 4 tonnes, was dragged 55 metres and flipped upside down. Two other cannon recovered by the company last year show fresh scratches from trawls and damage caused by friction from nets or cables.

“It turns out that Victory is right in the middle of the heaviest trawling area in the Western Channel,” Mr Stemm said.

Out of 34 survey boxes, each measuring 74 miles x 55 miles, more vessels were sighted in the area surrounding Victory than in any other. More than 66 per cent were beam trawlers, the most destructive.

The Times, Danny Fortson: The Scottish first minister has said the firth has the potential to turn Scotland into the Saudi Arabia of tidal energy.

For the past 16 years a rocky alcove on the shores of Stroma, one of the Orkney islands off the north coast of Scotland, has been the final resting place of the Bettina Danica, a 70-metre cargo vessel that ran aground in February 1993. All six crew were saved, but tugboats were unable to pull her back out to sea. After several attempts, they gave up.

Today all that is left is a rusting, crumpled hull, visible from passing ferries. It is not the only ship to meet such a fate. The remains of more than 60 vessels litter the rocks and seabed around this island, victims of the treacherous waters of the Pentland Firth. This stretch of sea between the tip of Scotland and the Orkney islands has some of the strongest tides in the world, created as surges from the Atlantic on one side and the North Sea on the other slosh through the strait that is only a few miles wide.

Yet shipwrecks aren’t all that lie beneath the roiling grey waters. Scottish first minister Alex Salmond has said the firth has the potential to turn Scotland into the Saudi Arabia of tidal energy, and the Crown Estates has begun an auction of parcels of seabed for tidal power developments. More than 40 companies are bidding.

Atlantis Resources, a small tidal turbine developer, is one of them. The company, led by Tim Cornelius, an Australian and former pilot of manned submersibles, has come up with a novel £400m project to build one of the world’s biggest tidal power plant there. Unlike other projects whose output would be pumped into the National Grid, Cornelius’s plan is to build a giant data centre onshore that would take all its power.

It sounds an off-the-wall idea, but one that he said tackles the biggest obstacle to development of Pentland Firth: its remoteness. Transporting power to areas of high demand, such as Edinburgh, would be costly. Even if it were possible, there is a nine-year waiting list for National Grid to connect a new project to the grid in Scotland - what Cornelius calls the GBQ, or Great Britain Queue.

The Times, Kieran Cooke: Every year in the UK we use about 600 million household or portable batteries. While re-use and recycling rates for larger batteries from the automotive and other industries are relatively high, almost all the smaller types, along with their cocktail of toxic substances, such as mercury, nickel and cadmium, are chucked in the bin and end up in landfill.

Next month, after an EU directive, regulations are being brought in aimed at putting an end to the dumping of hazardous waste and stopping the leaching of dangerous materials into the soil and water courses. Manufacturers, along with retailers, will in future be responsible for paying for battery collection, treatment and recycling. The aim is to collect 25 per cent of portable batteries, including rechargeable computer units, by 2012, rising to 45 per cent by 2016. Clearly this is going to result in industry restructuring: watch out for rising battery - and computer - prices.

Exactly how the new regulations will be implemented and in what way collection systems will work is far from clear. Gathering sufficient batteries to achieve economies of scale is one challenge. Public awareness campaigns are necessary.

There are many different types of battery, each made up of various materials. Recycling companies say they are particularly worried about handling non-EU batteries, especially those manufactured in China, which often contain higher than permitted levels of mercury. This can make recycling a more hazardous and expensive process.

The Times: Sir David Attenborough said yesterday that the growth in global population was frightening, as he became a patron of an organisation that campaigns to limit the number of people in the world.

The television presenter and naturalist said that the increase in population was having devastating effects on ecology, pollution and food production.

“There are three times as many people in the world as when I started making television programmes only a mere 56 years ago,” he said, after becoming a patron of the Optimum Population Trust (OPT) think-tank.

“It is frightening. We can’t go on as we have been. We are seeing the consequences in terms of ecology, atmospheric pollution and in terms of the space and food production. I’ve never seen a problem that wouldn’t be easier to solve with fewer people, or harder, and ultimately impossible, with more. Population is reaching its optimum and the world cannot hold an infinite number of people,” Sir David, who has two children, said.

The OPT counts among its patrons the environmentalist Jonathon Porritt and the academic Professor Sir Partha Dasgupta. However, Sir David’s appointment has already been criticised. Austin Williams, author of The Enemies of Progress, said: “Experts can still be stupid when they speak on subjects of which they know little.

The Times, Philip Beresford: The global rich are going green as never before. This first Sunday Times Green Rich List shows that the enthusiasm among the world’s wealthiest for investments in areas as diverse as electric cars, solar power and geothermal energy is unaffected by the recession.

The Green List has unearthed 100 tycoons or wealthy families worth £200m or more who have made either serious investments in green technology and businesses or hefty financial commitments to environmental causes. In total, the Green 100 are worth nearly £267 billion.

This enormous sum demonstrates that many of the world’s richest tycoons and entrepreneurs have embraced environmentalism. Indeed, our list is dominated by America’s wealthiest financiers and entrepreneurs such as Warren Buffett (worth £27 billion) and Bill Gates (worth £26 billion).

These two canny investors, who regularly swap places at the top of Forbes magazine’s annual list of world billionaires, have spent some of their financial firepower on areas such as wind power and electric cars in Buffett’s case, while Gates has backed alternative fuels such as oil from algae. We are not talking trifling sums here. Buffett has invested $230m in the Hong Kong battery-maker BYD.
