A viewpoint to COVID 19 virus: natural conservation also contributes to the prevention of epidemic virus from breaking out, because there are more diversity in natural microbes which compete with this epidemic virus within the community of the same ecological niche, reducing epidemic events. The mono-strain of microbes increases epidemic risks.

From above viewpoint, the broad scope and large scale of epidemic COVID 19 virus, which exceeds the historic epidemic events in the past, reflect that the biodiversity decreases in natual microbe community.

Specifically urban biodiversity conservation is mostly closed to the human health.

A viewpoint to Invasive Species VS. Exotic Species:
As warned by Biodiversity conservation guidelines by UN Biodiversity International Organization, it is not to introduce exotic species into native ecosystem, which may become invasive species. For the well-maintained ecosystem, introducing exotic species by human disturbance usually is considered to be detrimental. However, with the natural environmental change in the long term, the community of indigenous specie goes through natural succession process, which is replaced by exotic speices. Sometimes these exotic species is introduced by other animals (such as birds with migrated habits) as well. This is the reasonable natural selection process driven by the inter-species competitions, because the purpose of biodiverstiy conservation is not due to the mercy nature. However, human disturbances in terms of introducing exotic species is not allowed in most cases.
However, for the restoration of degraded or deforestation ecosystem, if the indigenous species can hardly maintain the functions of native ecosystem due to the environmental change in regional or global scales, introducing exotic species is an alternative to restore the ecosystem. In this case, the biomass production and the ecosystem functions (such as prevention of soil erosion or reserving rainwater) are the primary principles for the restoration.

A viewpoint to Gene Conservation VS Gene Pollutants
For the gene diversity conservation, it is to maintain the purity within dominant genetic variety as the first criterion. If the sub-population within dominant genetic variety is sustainable and plays a role in significant ecological functions at the local scale, the introducing exotic gene matarials from minor genetic sub-populations becomes a gene pollutant; However, if the dominant genetic population faces endangered status due to natural environmental change or it is degraded as not to maitain significant ecological functions, inter-varieties hybridization would be the right conservation practice.
For the existence of minor sub-populations of genetic varieties, if the genetic similarities is lowered than dominant species, it indicates unsustainable populations. The minor sub-populations may go towards purity in genetic similarity due to intra-species competitions under environmental change. However, reserving the minor genetic varieties in gene pool is also essential to genetic conservation.

If the life science is lifted to life signals (bio-electrowaves) viewpoint, it is at the soul level.

Why this becomes gene pollutant?
For the example of environmental adaptiveness, the genome traits of specific environmental adaptiveness (such as wide and deep root system in a specific soil condition) is sustainable when the genetic similarity maintains purity bloods as a whole population. In this case, any hybridization will lead to traits loses in this specific environmental adaptation. This gene hybridization is considered as gene mutation in a gene pool of dominant population or invasive gene materials by human disturbance.
