There's lots that can be done to help animals and wildlife in particular through making the right choices on a day to day basis.
What I mean is that every day, the way we live affects wildlife. We can choose to go vegetarian or vegan all the time or two or three times a week or once a month. We can choose to grow wildlife friendly flowers in our gardens. We can choose to shower instead of taking a bath and reduce our demand on the water supplies. We can buy palm oil free products and reduce our need to cut down forests and so destroy the homes of the animals living there such as the orangutan.
This page will give you some ideas as to choices you can make which will help us buy and live with the consequences for wildlife in mind.
