Aquaculture is seen as a sustainable way to produce fish. But are farmed salmon better than wild fish?

4 images of some fish such as koi that live in freshwater river and lake environments and in freshwater aquariums and garden ponds

14 images of some fish such as lion fish, grouper and sharks that live in saltwater environments like oceans, saltwater lakes and aquariums

8 images of some flowerheads such as roses and water lilies whose outer petals are longer than the petals in the centre of the flower

3 images of some asymmetrical flowerheads such as an iris and an Orchis Sima or Monkey Orchid

When fertilizers from agriculture get into lakes and rivers, big problems can result for aquatic ecosystems, food chains & webs!

5 images of invertebrates such as spiders and scorpions characterized by having 4 pairs of segmented legs, 2 main body parts and simple eyes

Wind power is a growing source of electricity generation. But wind projects often affect local wildlife populations, and researchers are using environmental monitoring techniques to alleviate some of these impacts.

4 images of some birds such as emus and penguins that have less developed or small wings and have evolved over time not to be able to fly
