Should we always protect and increase biodiversity?

Biodiversity, formed from the words “biological” and “diversity”, refers to the diversity of life in a particular area, whether that is a backyard or a whole country or the entire earth. One example of a biodiversity measurement is bird watchers listing the species they see in an area on a given day. As Wilson put it, Biodiversity is: “The totality of hereditary variation in life forms, across all levels of organization, from genes to chromosomes within individual species to the array of species themselves and finally at the highest level, the living communities of ecosystems such as forests and lakes." Currently, animal and plant species are becoming extinct at an even faster rate than the dinosaurs' disappearance millions of years ago.

We need biodiversity for food, medicine and future advances

Over the last 25 years, 70% of new molecule drugs have come from natural sources. A wide diversity of plants and animals helps us develop new drugs, provides us with food and other desired products, such as fertilizer, silks, oils and adhesives. Some species of animals help us control invasive species like rats so we don’t have to resort to poisons to lower pest levels, and many Wild animals and plants are sources of genes for hybridisation and genetic engineering. These diverse conditions could hold much in the way of future potential, with many new discoveries likely to come, but not if they are destroyed by us. For example many people think there may be a cure for cancer to be found in the Amazon Rainforest, but we will never find that if loggers and industrialist continue to destroy the rich environment there. As “Sayonara16” says: “We should conserve it until we know what not conserving it will mean to us”

We need biodiversity because lack of it could cause problems

By preserving biodiversity we could save money on the NHS and other public health services. The animals that play host to mosquitoes and ticks will go unchecked by predators if the predators are driven from their habitat by deforestation and other destructive behaviour on our part. Hence, rises in Malaria and other diseases carried by parasites could increase dramatically costing health services millions.

Another example is: small, separate patches of forest and grassland cannot support large roaming predators like coyotes, allowing small prey animals such as ...
