You know, because all that CO2 plant food is bad for plants
Climate change is making plants less nutritious ? that could already be hurting animals that graze
More than one-third of all animals on Earth, from beetles to cows to elephants, depend on plant-based diets. Plants are a low-calorie food source, so it can be challenging for animals to consume enough energy to meet their needs. Now climate change is reducing the nutritional value of some foods that plant eaters rely on.
Human activities are increasing atmospheric carbon dioxide levels and raising global temperatures. As a result, many plants are growing faster across ecosystems worldwide.
Here we go
Some studies suggest that this “greening of the Earth” could partially offset rising greenhouse gas emissions by storing more carbon in plants. However, there’s a trade-off: These fast-tracked plants can contain fewer nutrients per bite.
“Suggest”. In other words, they do not know. It’s all conjecture. So, it is fearmongering and not science.
We believe long-term changes in the nutritional value of plants may be an underappreciated cause of shrinking animal populations. These changes in plants aren’t visually evident, like rising seas. Nor are they sudden and imminent, like hurricanes or heat waves. But they can have important impacts over time.
You can believe all you want. Some people there are bigfoots and yetis. Neither is proof.
Over the longer term, it will be important to understand how nutrient dilution is altering entire food webs, including shifts in plant species and traits, effects on other animal groups such as predators, and changes in species interactions. Changes in plant nutritional value as a result of rising carbon dioxide levels could have far-reaching impacts throughout ecosystems worldwide.The Conversation
So give us lots of taxpayer money to study this, especially so we can travel a lot.
