Pollution

Pollution is the introduction of contaminants into the natural environment that cause adverse changes. There are three main types of pollution: air, water, and land pollution. Air pollution occurs when harmful substances are added to the air, affecting human health and contributing to issues like climate change. Water pollution happens when toxic substances contaminate bodies of water, threatening biodiversity, food safety, and access to clean water. Land pollution deteriorates the earth's surfaces through the accumulation of solid and liquid waste in soil and groundwater, endangering habitats, water quality, and public health.
