Solar farms and pollinators

September 30, 2024 By EarthWise Leave a Comment

Two important environmental challenges are finding some literal common ground: the need to reduce carbon emissions and the fight to stave off global biodiversity collapse. Both issues can be addressed at solar farms.

Solar energy is an important weapon in the battle against climate change. But utility-scale solar farms take up large amounts of land. Large-scale solar farms already take up nearly a thousand square miles of land in the US and will take up much more in the coming decades.

In the meantime, the biodiversity collapse is being driven in large part by habitat loss.

Given all this, solar farm operators, biologists, and environmentalists are teaming up to grow pollinator-friendly plants in and around solar farms. The plantings attract insects, birds and even mammals. The more plant diversity in the solar farms, the more environmental benefits can be achieved.

There are costs associated with creating pollinator-friendly solar farms. Ideally, solar panels need to be installed at greater height than otherwise in order to permit growing many of the plants that attract bees and butterflies. But there are economic benefits associated with attracting and sustaining pollinators. On a cautionary note, there have already been cases of greenwashing, where solar operators claim environmental benefits far in excess of the scope of the actual efforts they have made.

There are both governmental and non-governmental agencies seeking to assess and certify pollinator-friendly solar farms. There is considerable variability in the ecological value of existing farms. Pollinator-friendly solar farms are in their early days, but they have a lot to offer as a win-win strategy for the environment.

Climate change lawsuits

May 7, 2024 By EarthWise Leave a Comment

For the better part of a decade, there have been lawsuits against fossil fuel companies for their actions related to climate change. The Center for Climate Integrity, a nonprofit that provides legal support to communities suing oil companies, has tracked 32 cases filed by state attorneys general, cities, counties, and tribal nations against companies including Exxon Mobil, BP, and Shell.

There has been extensive news reporting about oil companies’ efforts to undermine the scientific consensus about the climate as well as revelations about oil companies hiding their own research over decades projecting the dangers of climate change.

Oil companies have long sought to shut down the lawsuits or move them from the state courts where they were filed to federal courts where they believe national regulations could override local governments’ claims against them. But a string of circuit court and U.S. Supreme Court decisions have ruled that the cases alleging violations of state laws do belong in state courts.

The first case to reach trial will likely be a Massachusetts case against Exxon Mobil and that could happen as soon as next year.

What do these lawsuits seek? Some seek to force oil companies to pay for the past and future damages caused by climate change that are costing states and communities billions of dollars. Others seek to stop defendants from making false and misleading statements about the effects of burning fossil fuels, from greenwashing their own activities, and to fund corrective education campaigns.

The first trials could lead to a tidal wave of new cases, similar to what happened in the 1990s when tobacco companies were forced to pay billions of dollars under legal settlements.

Planting Millions Of Trees Isn’t So Easy | Earth Wise

November 11, 2022 By EarthWise Leave a Comment

There are initiatives around the world to plant millions of trees as a way to fight climate change. Unfortunately, scientists have observed that many of these projects are ill-conceived and poorly managed. Some have failed to grow any forests at all.

One such project was an attempt to plant a million mangrove seedlings in coastal mud on the Filipino island of Luzon in 2012. Ten years later, less than 2% of the trees have survived. The other 98% have died or have washed away. The problem was that the site of the project was ecologically unsuited to mangroves because it is too waterlogged and there is no oxygen available except in a few sheltered spots.

In 2019, the Turkish government managed the planting of 11 million trees in 2,000 sites across the country. A later survey found that 90% had died, although the government denies that assertion.

Many other projects have also had dismal results. The causes of failure vary but include planting single species of trees that become vulnerable to disease, competing demands for land, changing climate, planting in areas not previously forested, and lack of ongoing care for the saplings including watering them.

Nobody is opposed to mass tree planting. There is no anti-tree lobby. But tree planting is sometimes a form of greenwashing. It is great for public relations but unless it is done properly with appropriate planning, it can be a waste of effort and money. The result can be a phantom forest that does nothing for the climate.

Forest planting can work if the social and environmental conditions are right, and if planting is followed by long-term monitoring and care of the trees.

Bidding ‘Adieu’ To Single-Use Plastics | Earth Wise

July 27, 2022 By EarthWise Leave a Comment

Since the 1950s, more than nine billion tons of plastic have been produced, and 50% of that has been during the past 15 years. While there are some use cases for plastic that are important, it generally serves as the poster child of our throwaway culture.

Plastic pollution can be found everywhere on earth, from the top of the tallest mountains to the bottom of the deepest oceans. It’s in our food, water, and air.

By 2040, researchers predict that there will be nearly 90 million tons of plastic pollution entering the environment each year. By some estimates, single-use plastics account for half of all our plastic waste.

Many cities, states, and even countries are limiting or even banning single-use plastics. Canada recently announced a ban on single-use plastics. The ban includes things like plastic shopping bags, cups, cutlery, straws, stirrers, and take-out food containers.

The ban will phase in over the next several years, beginning with a ban on the manufacture and import of single-use plastics by the end of this year. Sales of these items will be prohibited in 2023, and the export of plastics will cease by the end of 2025.

Canada’s southern neighbor, the United States, leads the world in plastic waste generation. While some states have approved single-use plastic reforms, most of the effort at the federal level has focused on improving recycling rates. However, a recent report from several environmental organizations found that plastic recycling rates in the U.S. have actually declined in the last several years, from an already-dismal 8.7% to less than 6%.

Suggesting the plastic waste problem can be solved with improved recycling rates is greenwashing the issue.
