That’s the point, they’re trying to frighten you so that while the elite enjoy all the excess wealth provides, you don’t have kids and live like a hermit. They are selling #TheGreatReset of capitalism pushed by the World Economic Forums and United Nations.

Even one single thing that seems comparatively irrelevant can harm the ecosystem, and I think it's important to know that. For example, specifically killing many of a specific species of fish will disrupt the food chain that they reside in, affecting further animals. And when the food chain is messed up and is not acting according to nature, the balance of the world is gone.

Actually electric vehicles are not so environmentally friendly. They are just as harmful. Think of the manufacturing process of these vehicles and the manufacturing of the batteries that these vehicles need in order to run. Also take into account where they are being manufactured and if they have to be transported to another country. It actually causes just as much pollution. Definitely look into how this is affecting our climate.

That’s going to be entirely up to the individual. If you’re able to give 4-5 hours a day (Spread out), that’s a decent start, and possibly working up to 6 hours a day.
