question: which factors influence the use of complementary and alternative medicine?

In the latter part of the 20th century, the validity of social sciences became widely accepted. Some branches of social science researchers researched and documented the role of complementary and alternative medicine [CAM] in society. Their actions helped to address the issues of missing data and evidence to support medical claims, which contributed to a …

question: how are plants propagated?

Sexual Reproduction New plants are created via plant propagation of which there are two types: sexual and asexual. With sexual propagation, there are two sources of parental DNA resulting in the creation of a third living organism. Sexual propagation involves the floral components of the plant and is the result of the pollination of megagametophyte …

geoengineering explained: the benefits and challenges of biochar

Biochar, a form of carbon dioxide sequestration (SDR), is a solid material obtained from the carbonization of biomass. This process produces highly porous charcoal. The biomass is then buried to lock the carbon into the soil which can improve soil functions. CO2 typically produced by the natural degradation of biomass is also reduced. This practice is …

geoengineering explained: the benefits and challenges of enhanced weathering

Enhanced weathering is the process of exposing large quantities of minerals that are reactive with carbon dioxide in the atmosphere and storing the resulting compound in the ocean or soil. It is considered a form of carbon dioxide removal or CDR. BENEFITS CHALLENGES Has the potential to increase terrestrial and oceanic net productivity Can be …

geoengineering explained: the benefits and challenges of ocean alkalinity enhancement

Ocean alkalinity enhancement is increasements in the ocean's alkalinity via the exposure of large quantities of reactive minerals to carbon dioxide in the atmosphere. Calcium oxide is created when temperatures of ca. 1000 degrees Celsius are used to heat high purity limestone. The Calcium oxide is then stored in the ocean. The water prevents the …

geoengineering explained: the benefits and challenges of stratospheric aerosols

Stratospheric aerosols are minute particles suspended in the atmosphere designed for solar radiation management [SRM]. When these particles are sufficiently large, their presence becomes noticeable as they scatter and absorb sunlight, which can reduce visibility [haze] and redden sunrises and sunsets. Aerosols interact both directly and indirectly with the Earth's radiation budget and climate. As …

geoengineering explained: the benefits and challenges of space reflectors

Space reflectors, a form of solar radiation management [SRM], are sun shields positioned in space in order to reduce the amount of solar energy reaching the earth. Options include placing mirrors around the earth, placing millions of reflectors between the earth and the sun where the gravitational attraction between the two bodies is equal, launching a …
