I've felt the impact. When I was a kid going up North for the summers meant hiding out from the blackfly swarms, battling horse flies, catching pollywogs, and watching out for moose. There are no pollywogs anymore, I haven't seen a horse fly in years and frogs are pretty rare to see. You can find polar bears digging in the trash where you'd never see them before.

I don't know if changing our eating habits will help regenerate biodiversity or at least slow down the reduction of it but there are some easy things we can do, that if we all do them, that could have a big impact on the world in a positive way:

1. Go veggie. Or at least try going veggie one or two days a week. Many commodity crops are grown for cattle feed which leads to deforestation and reduction in biodiversity and is a factor in anthropological climate change.

2. Reduce your reliance on biofuels and fuels in general. Palm and canola oil lead to deforestation, monocrops, pesticides, herbicides, etc. The economic incentives and numbers of scale have decimated entire ecosystems for these crops. If able and it makes sense try asking about remote working, use car sharing, demand transportation and cycling infrastructure. Check the provenance of your chocolate, beauty products, for canola, palm, etc oils and buy alternatives without those ingredients.

3. Support philanthropic efforts to protect and restore wildlife and land. Support indigenous rights: there are plenty of corporations exploiting indigenous land and betting on the local governments and people turning a blind eye.
