Air pollution causes around 7 or 8 million deaths each year. [ 5 ] [ 6 ] It is a significant risk factor for a number of pollution-related diseases , including heart disease , stroke , chronic obstructive pulmonary disease (COPD), asthma and lung cancer .
The authors estimated that climate change was projected to cause an additional 250,000 deaths per year between 2030 and 2050 but also stated that "these numbers do not represent a prediction of the overall impacts of climate change on health, since we could not quantify several important causal pathways".

In 2016, the WHO recorded 56.7 million deaths [3] with the leading cause of death as cardiovascular disease causing more than 17 million deaths (about 31% of the total) as shown in the chart to the side. In 2021, there were approx. 68 million deaths worldwide, as per WHO report.
Diseases caused by pollution, lead to the chronic illness and deaths of about 8.4 million people each year. However, pollution receives a fraction of the interest from the global community. [1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
Environmental epidemiology is a branch of epidemiology concerned with determining how environmental exposures impact human health. [1] This field seeks to understand how various external risk factors may predispose to or protect against disease, illness, injury, developmental abnormalities, or death.

According to the World Economic Forum, an increase in drought in certain regions could cause 3.2 million deaths from malnutrition by 2050 and stunting in children. [246] With 2 °C warming, global livestock headcounts could decline by 7–10% by 2050, as less animal feed will be available. [ 247 ]
