Human activities have many negative effects on the environment and one of the most obvious is threatening biodiversity. Species go extinct, or are on the verge of extinction, due to reckless hunting, fishing, habitat destruction, pollution, climate changes and so on. What can be done to stop this trend?
Changing Our Economy
Modern economic activities have the worst impact on wildlife. What can we do?
- Cut down pollution – our industry releases lots of toxins in the environment, killing many organisms.
- Recycle – not only toxins affect the environment, but also non-biodegradable waste and the continuous exploitation of resources, in order to produce new goods.
- Equity – an unequal economic system means that many people in various parts of the world still rely on the local biodiversity to support all their needs. A more equitable economic system would mean less poverty and less overexploitation of natural resources.
Implementing Conservation Means
Wild species need protected areas, where they can regenerate their populations in peace.
This means natural reserves, parks, marine protected areas, corridors and others. All these need to be backed by proper legislation and regulations and, where it is necessary, financial incentives. But, all these measures need to be really implemented and not remain just figures on paper.
Changing Our Agriculture
There are quite some problems with our current agriculture. First of all, expanding cultivated fields is usually done by destroying natural ecosystems. Furthermore, bad planning leads to soil erosion, so the land quickly becomes unsuitable for agriculture and new areas need to be cleared. By destroying natural ecosystems, we obviously threaten biodiversity. What needs to be done?
- Increasing efficiency – this means more productivity on the same land area.
- Searching for new crops – more efficient, more resistant to local conditions in each part of the world.
- Mixing crops – by conserving part of the natural vegetation (agro-forestry) and cultivating various plants in the same area (intercropping), we open way for a sustainable agriculture that conserves part of the original wildlife and protects the soil.
- Valuing small land areas – by overcoming the obsession for large-scale agriculture, we can greatly improve the overall efficiency.
Stopping Anthropogenic Global Warming
Climate changes threaten wildlife, just as they threaten our assets and our way of life. By developing new technologies and implementing penalties for carbon dioxide release into the atmosphere, we can stop this phenomenon.
Humans are part of the global biodiversity and whatever affects wildlife also affects us.
