1. Climate change
The biggest threat to ecosystems, global warming is affecting natural systems at a rate that’s faster than we’ve imagined. Trees that produce the oxygen we breathe are being cut down in favour of land to grow or dispose of food. This is happening whilst landfills that hold decomposing food waste are to producing methane; a greenhouse gas that contributes towards global warming.
2. Wildlife extinction
Studies have shown that the majority of food wastage is made up of fruit and vegetables. Food wastage attracts wildlife, which can be harmed by these decaying foods. This affects their numbers, reproduction patterns and predator-prey relationships.
It is estimated that over 7 billion tons of wasted fishery is dumped into the ocean every year. This attracts seagulls in particular, who then feed on this fish. The more seagulls there are, the greater risk there is to local fish and other species, taking the ecosystem out of its natural balance.
