The atmospheric concentrations of CO2 during Earth's past have always been changing, sometimes slowly, sometimes abruptly. The changes continue to the present day, and will continue in the future. The reasons for the oscillations in the CO2 levels are numerous, but while in the past they have been exclusively from natural causes, in modern times it is also the humans that got involved in it. The Cretaceous period had 1000 ppm of CO2, while the Eocene had 560 ppm of CO2. In the present, the CO2 concentrations are 405 ppm, thus significantly lower than the Cretaceous and Eocene. What can be learned from these two periods though is that such high concentrations of CO2 result in much warmer global climates, with ice sheets lacking, and the temperatures being much more equalized across the latitudes. If the current trend continues, there is every chance that our planet will experience such changes in the near future.
Answer:
Public healthcare.
Explanation:
Public healthcare is the set of measures and policies designed to meet the health and medical needs of the population, through government action and through the use of public money. Thus, the financing of hospitals, clinics, vaccination plans, etc., by the government, is part of this concept. Its objective is to guarantee access to health for the majority of the population, to prevent the spread of diseases and guarantee a higher standard of living for people. This type of measures is usually financed through the taxes that the government collects, with which countries with this type of system usually charge higher taxes to their citizens, as is the case of Canada.
