The way to do it is for more to die than being born. Whales commonly die due to human activity. For example, whales are commonly killed for their meat.
Three ocean carnivores are sharks, killer whales, and giant squids. These predators play a crucial role in maintaining the balance of marine ecosystems by controlling the population of other marine species.
Overfishing of small fish would decrease their population the most since it directly reduces the number of individuals in the population.
Implementing comprehensive sex education programs, increasing access to contraceptives, promoting women's education and empowerment, improving healthcare services, and addressing socio-economic factors can help reduce population growth in developing countries.
A severe drought in a grassland will reduce the availability of food for herbivores, leading to a decrease in their population. This will in turn decrease the population of predators that rely on these herbivores for food. Consequently, there will be fewer consumers in the energy pyramid as the trophic levels are interconnected.
Disease outbreaks and limited resources can reduce population size by increasing mortality rates and limiting the availability of food and water for a population. Environmental disasters like droughts or floods can also lead to a decrease in population size by disrupting ecosystems and habitats.
Whales don't reduce carbon .
There are about 3000 killer whales in the world.
Their population number is between 34,000 and 52,000 Humpback Whales.
Their population number is between 18,000 and 30,000 Gray Whales.
Their population number is between 440,000 and 1,370,000 Pilot Whales.
Their population number is between 34,000 and 52,000 Humpback Whales.
If you want a specific species then it varies. Some whales population are known but some are not known well. Example, population humpback whales is around 19,000. Whereas minke whales are around 800,000 to 1 million.
The 2013 population number is between 10,000 and 25,000 Blue Whales.
It is estimated that there are about 8,000-14,000 blue whales worldwide
