Biodiversity and the effect of human interaction on ecosystems
Biotechnology is changing the world. We no longer have complete dependence on some foods.
GM crops can provide extra nutrients.
Genetically modified bacteria is used to create insulin
The fungus Fusarium is used to create pseudo meat.
We are being very unsustainable with our fishing.
Lots of fish are disappearing. We need larger holes in nets, and we need to stop fishing during breeding season
Factors affecting food security
Increasing population, changing diets, pests, human conflict.
Some factors include:
This is with breeding progreammes and habitat restoration and increasing field margins
Humans are trying to reverse our effects on Biodiversity
Cattle and rice farming produce lots of CO2
This reduces biodiversity, and also provides space for cattle and rice farming
Humans are destroying peat bogs, which release lots of CO2, and also reduces biodiversity.
Humans are using up more space for farming 1 crop, reducing biodiversity.
Some of these chemicals damage the environment
Chemicals that cause damage are sewage, fertiliser, pesticides, nitrogen oxides (acid rain)
More humans mean more chemicals used
Humans are destroying biodiversity w/ deforestation and global warming
A good biodiversity stabilises ecosystems by allowing predators to rely on more than one species of prey
Biodiversity is the variety of different organisms within an ecosystem.
