The grid-table indicates the level of impact that each of the 5 drivers of biome and ecosystem degradation have had over the last
century. The arrows indicate the current trend of each driver on the particular ecosystems. According to this grid-table, which driver
currently seems to be the most under control and what have humans done to help control the impact it has on the Earth's
ecosystems?

the amount of non-native animals and plants that are introduced to stable
ecosystems.
Over-exploitation; Laws are in place to aid in the conservation of the
natural resources which include the licensing of wild game hunting and
fishing along with the creation of national parks to protect vital
ecosystems

manufacturing along with the increase use of clean nuclear energy. Both
reduce the amount of green-house gases that are being released into the
Surrounding environment
