Assess the impact of human activity on a biome that you have studied - Leaving Cert Geography - Question 18 - 2006

1. Deforestation: The removal of large areas of trees for timber and to clear land for agriculture results in habitat loss, increased carbon emissions, and changes in water cycles.

   2. Agriculture: The expansion of agricultural land often leads to monocultures, which decrease biodiversity and soil fertility. This practice also contributes to the overuse of fertilizers and pesticides, resulting in soil degradation and water contamination.

   3. Urbanization: Expanding cities disturb natural habitats and lead to pollution, habitat fragmentation, and increased human-wildlife conflicts.

The combined effects of these human activities lead to significant ecological changes, including the loss of species, alteration of ecosystem services, and changes in climate patterns. For instance, the loss of tree cover in rainforests not only threatens species but also threatens global climate regulation, as these areas are crucial carbon sinks.

In conclusion, human activities have profound and often negative impacts on biomes, specifically through deforestation, agriculture, and urbanization. These actions compromise the integrity of the ecosystem, leading to biodiversity loss and hindered ecosystem functions. It is essential to adopt sustainable practices in order to mitigate these impacts and preserve biomes for future generations.
