Humans are not alone in having to deal with the effects of climate change. Animals—wild, domesticated, on land and in water, along with insects and all other forms of life face new existential threats because of manmade causes.

Their habitats are changing and shrinking due to glaciers melting, sea levels rising, flooding, increasing droughts, worsening heat waves, and forest fires—which are bigger and longer lasting. And on top of all that, humans are developing previously forested areas for housing and farming, which further marginalizes wildlife from their natural homes and food supplies.

All life depends on a healthy planet, and only humans have the ability to remedy these troubles. It’s time we each change our habits and expectations of life.

Start with small steps. Discuss ideas with family, friends, and colleagues.

The good news is: we can make a difference. We just need to choose a first step and take it. All of planet Earth’s inhabitants need us to act now and not wait for someone else to fix the problems.
